Did you know the latest American hostage held by ISIS is a Muslim

Peter Kassig, an American is also an American Muslim who went to Syria to HELP Syrians not fight them and he is the latest hostage of the terror group ISIS to be threatened with death. In a letter to his parents he talks about how he is at peace with his religion and his decisions he made that took him to Syria but also that he is afraid of the uncertainty of death at the hands of this terror group. Is there anyone who still thinks the group has anything to do with Islam? It kills its native sons from all over the world; sounds more fascist than Islamist.
